All of these pictures were the first Google Image result for French man, French woman, Mongolian woman, Mongolian man, Korean man and so on (except in cases where there was explicit nudity or violence, for which I chose the second image). What you end up with is a gallery of (mostly) stereotypes of what people in different countries look like. (Note that Google results vary from time to time, country to country.)
*Google's define operator explains the meaning of the word "stereotype":
"An exaggerated image of the characteristics of a particular group."
"[A] negative or limiting preconceived belief about a certain type of person that is applied to everyone in that group."
"[A] mistaken idea that many people have about a culture different from their own."
